- Considering the 3 following declarations:
-
- 1 - char **foo;
- 2 - char *foo[];
- 3 - char foo[][];
-
- I know that there is a (big !) difference in memory reservation, but I do not know
- if foo IS or IS NOT of the same type in these three cases.
-
- To summarize my question :
- Is the first one securely usable for casting a variable of the third kind, when
- calling a function where it is defined as the second kind ?
-
- Follwing is a description (the 2 functions are in differents sources files) :
-
- myexample()
- {
- char foo[MAX_X][MAX_Y];
- ...
- myfunc( (char **)foo );
- }
-
- void myfunc( char *foo[MAX_X] )
- {
- ...
- }
-
- Can anybody help me ? Is it system-dependent ?
-
- Many thanks in advance,
-
- Philippe.
